To configure PostgreSQL for OLTP on that hardware, I would strongly recommend the use of a connection pool which queues requests above some limit on concurrent queries. My guess is that you'll see best results with a limit somewhere aound 40, based on my tests indicating that performance drops off above (cpucount * 2) + spindlecount. I wouldn't consider tests of the other parameters as being very useful before tuning this. This is more or less equivalent to the "engines" configuration in Sybase, for example. -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
